Abstract

In a method for determining an exhaust gas recirculation amount for an internal combustion engine having a cylinder with an intake duct and an exhaust duct, wherein an outer exhaust recirculation amount is determined from an exhaust gas temperature, a fresh gas temperature, a fresh gas amount and an inner exhaust gas recirculation amount, and wherein the inner exhaust gas recirculation amount takes the combustion gas amount into consideration which during a charge change remains in the combustion chamber of the internal combustion engine.
